Solution

Verified by Toppr

Correct option is D)

Time period of pendulum $T = 0.20$ s
Thus frequency of pendulum $f = \frac{1}{T} = \frac{1}{0 . 2 0} = 5$ Hz

The time -period of a simple pendulum does not depend on

A simple pendulum of length 1 m is oscillating with an angular frequency 10 rad/s. The support of the pendulum starts oscillating up and down with a small angular frequency off 1 rad/s and an amplitude of $10^{- 2} .$ The relative change in the angular frequency of the pendulum is best given by:
